T 0 all whom it may concern:

Be it known that we, GEORGE PAYNE and JOHN Ross, both of the town of Orillia, in the county of Simcoe, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Water-Hydrants, of which the following is the specification.

Our invention relates to improvements in water hydrants, and the object of the invention it to devise a hydrant for lawn and house use, which will not be liable to freeze and which will be simple, positive and effectual in operation and it consists essentially of a casting having the inlet at one side at the bottom and the outlet extending upwardly at one side from the top, tapered seats located in the valve one above the other and a valve stem in two portions having tapered valves constructed as hereinafter more particularly explained.

The invention is shown in the accompanying drawings, in which Figure l is a vertical section through the improved hydrant and Fig. 2 is a central cross section thereof.

A is the body casting, which has a tapered seat A at its upper end for the upper leather stop valve B. The body casting A is provided with an internal thread A at its lower end to receive the nipple A in which is formed the tapered seat B 0 is the reducing elbow, which is screwed on to the nipple A and is provided with an internally threaded outer end C D is the upper end of the valve stem, which is provided with an enlarged lower portion D hollow and provided with an internal thread D The upper end of the valve stem B is provided with a thread D and reducing terminal taper D preferably square in cross section. The tapered valve B fits between the shoulder D formed by the enlarged lower portion D, and the nut E screwed on to the threaded portion D of the valve stem D.

The thread D is a uick acting pitched thread for receiving t e male thread F formed at the upper end of the stem F, which is provided with wings F fitting in recesses A formed in the side walls of the orifice A and extending above the tapered valve seat in the nipple A The wings allow of a sliding but a non-rotating connection between the valve stem and the nipple A 4 The wings also form shoulders F against which abuts the lower tapered valve G.

H is a washer and I is a nut, whereby the lower tapered valve is held in position.

The body casting Ais formed with a branch outlet A provided with an internal thread as indicated. It is to be understood that the stems D and F are provided with a right hand thread and the operating end of the stem D is given a left hand motion and by being given a left hand motion will cause the stem F to recede from the stem D and open the lower valve G, thus letting the inlet water find an entrance through the nipple A by means of the opening therein. If the valve mechanism is now closed again until the lower valve G is seated no more water will be admitted. Upon a still further right hand turning of the stem D the upper valve A will be caused to descend and allow all the entrapped water above the lower valve to escape as will be readily understood. It will thus be seen that a means is afforded of getting rid of the standing water in the spout pipe connected to the branch outlet A". The tapered portion D is for the purpose of receiving the usual key socket for manipulating the valve.

Such a hydrant as we describe is simple, readily operated and not liable to get out of order, and effectually disposes of the liability of the water freezing in the hydrant, which is the important desideratum we have attained in our invention.

What we claim as our invention is:

In a hydrant, the combination with a body casting having a branch outlet at the top extending vertically upward on one side of the center of the casting and a center opening extending through the center of the top of the casting and flaring outwardly and downwardly, of a nipple secured into the bottom of the casting rovided with a central tapered valve seat iaving a central orifice extending from the top of the seat to the top of the nipple, vertical recesses formed in the sides of the orifice, an elbow screwed on the nipple, a two-part valve stem having an enlargement therein provided with an interiorly threaded portion and a tapered valve secured on the upper member of the stem above such enlargement and fitting within the central opening of the casing, a nut secured on the upper valve stem above the valve, such valve stem terminating in a squared tapered end, a nick pitch thread designed to seat itself" within the tapered 10 formed on the lower mem er of the two-part seat of the nipple, and a nut and washer for valve stem and fitting at the top within the holding the lower tapered valve in position. internally threaded portion of the enlarge- E PAYNE ment of the upper valve stem, radial wings N ROSS extending from the lower stem member and designed to fit within the recesses formed in Witnesses:
